説明
このプリミティブは, コンパイル済みの Scilab 関数function-name
を関数を内部表現にコード化したツリー (鱗状のtlists)に変換します.
tree2code()
と共に使用します.
例
prog = macr2tree(log2); // Note that the input is log2, not "log2" typeof(prog) fieldnames(prog)' prog.name deftxt = tree2code(prog, %T); printf("%s\n", deftxt);
--> typeof(prog) ans = program --> fieldnames(prog)' ans = !name outputs inputs statements nblines ! --> prog.name ans = log2 --> deftxt = tree2code(prog, %T); --> printf("%s\n", deftxt); function [f,e] = log2(x) [lhs,rhs] = argn(0) if rhs<>1 then msg = gettext("%s: Wrong number of input argument(s): %d expected.\n") error(msprintf(msg, "log2", 1)) end if argn(1)==1 then f = log(x)/log(2) else [f,e] = frexp(x) end endfunction
